Description

  The present invention relates to a tunnel disaster prevention system in which terminal devices such as a notification device and a detector installed in a tunnel are connected to a disaster prevention receiving board and an abnormality in the tunnel is monitored.

  Conventionally, emergency facilities have been installed in tunnels for exclusive use of automobiles and the like in order to protect people and vehicles from fire accidents that occur in the tunnel.

  Such emergency facilities are equipped with fire detectors, manual notification devices, emergency telephones for fire monitoring and reporting, fire hydrant devices for fire extinguishing and fire prevention, and tunnel enclosures and In order to protect the inside of the duct from fire, a water spray that sprays water for fire extinguishing from the water spray head is installed, and a disaster prevention reception panel that monitors and controls the terminal equipment of these emergency facilities is built to build a tunnel disaster prevention system doing.

  A tunnel disaster prevention system composed of a disaster prevention receiving board and terminal equipment is roughly divided into an R type transmission system and a P type direct transmission system. The R-type transmission method enables individual management in which a terminal device such as a fire detector having an address set on the transmission line is connected and detection and control are performed for each terminal device by transmission control. In the P-type direct transmission method, a plurality of terminal devices belonging to the same partition are connected to a signal line drawn out in each partition unit according to the type of terminal device, and detection and control are performed in signal line units.

  By the way, in the P-type direct transmission type tunnel disaster prevention system, terminal devices such as a manual notification device, a fire hydrant starting device, a duct temperature detector, etc. are configured with a signal output unit by operation or detection as a no-voltage a contact switch, A no-voltage a-contact switch is connected to the signal line drawn from the disaster prevention reception board. The no-voltage a contact switch is normally turned off in a monitoring state, and is turned on by an operation or detection operation to output a no-voltage contact signal.

  Specifically, the power supply voltage is applied from the disaster prevention receiver side to one of the signal lines via a pull-up resistor, and in a steady monitoring state in which the no-voltage a contact switch is turned off, current consumption almost flows through the signal line. First, the power supply voltage between the signal lines as seen from the disaster prevention reception board is maintained at substantially the power supply voltage. When the no-voltage a contact switch is turned on, current flows in the signal line, and the voltage between the signal lines as seen from the disaster prevention receiving board decreases to approximately zero volts. The disaster prevention receiving board increases the current consumption of the signal line or between the signal lines. A voltage drop is detected and a reception signal indicating operation or detection of the terminal device is output to the control unit.

  For example, if it is a fire notification signal from a manual notification device, the disaster prevention reception board performs control operations such as fire display, lighting control of the response lamp on the terminal side, manual notification section display, output of fire extinguishing pump start signal, and remote monitoring Fire notification signals are transmitted to external equipment such as control equipment, television monitoring equipment, variable road information board equipment, tunnel ventilation equipment, lighting equipment, etc., so that predetermined countermeasure control is performed.

Japanese Patent Laid-Open No. 2002-246962 JP-A-11-128381

  In such a conventional P-type direct-sending tunnel disaster prevention system, the signal line connecting the terminal equipment has been deteriorated due to deterioration over time of the signal line (external cable) connecting the terminal equipment. More current than expected in the normal monitoring state flows, and the disaster prevention reception board performs alarm operation by judging that the signal is received by the operation or detection operation of the terminal equipment, as well as remote monitoring control equipment, TV monitoring equipment, variable road Interlocking other equipment such as information board equipment, tunnel ventilation equipment, lighting equipment, etc., often prevents the passage of the tunnel.

  By the way, when a fire alarm is output by receiving a fire signal at the disaster prevention reception board, or when a failure in the signal line is detected and a fault alarm is output, the fire signal is output at the stage of subsequent investigation work. For a received fire line or a fault line in which a fault is detected, the measurement history measured by the current monitoring device may be displayed to check the state of the fire line or fault line.

  The current detection device periodically measures the current of the signal line, for example once a day, and stores it as a measurement history. However, a current value abnormality in which the measured current value is outside a predetermined threshold range is determined. In addition, there are line faults such as signal line disconnection and terminal equipment operation tests by periodic inspection, etc. under monitoring control of the disaster prevention reception board, and information such as line faults and line tests being included in the measurement history It is effective to read out the history information and check the state of the fire line or the faulty line.

  However, when incidental information such as a line failure or a line test is included in the measurement history, it takes time and effort to display and distinguish the measurement history with a huge amount of data measured periodically.

  In addition, a current monitoring device is provided in a separate housing for the disaster prevention reception board, so a transmission function and a processing function for sending fire information, fault information, etc. from the disaster prevention reception board to the current measurement device and storing them together with the measurement history There is also a problem that the equipment configuration and processing are complicated.

  The present invention integrates the function of the current monitoring device into the disaster prevention reception board to simplify the equipment configuration and processing, and displays the measurement contents when measuring and storing the signal line current value and displaying it. An object of the present invention is to provide a tunnel disaster prevention system that can easily and easily grasp that information such as current value abnormality, line failure, and line test is included.
